The median occurrence–period distributions from our models with (Scenario 4; dotted–dashed lines) and without (Scenario 1; solid lines) a treatment for unresolved stellar companions, using either (left) the observed companion rate and properties, or (right) the field companion rate and blend of observed/simulated undetected properties. Colors denote the marginalized distributions for either super-Earths (blue; 1–2 R_⊕), sub-Neptunes (orange; 2–3.5 R_⊕), or their combination for all small planets (black; 1–3.5 R_⊕).
